(Pack of 5) EL817 Optocoupler SMD 4 Pin IC
The EL817 SMD Optocoupler is a compact and reliable phototransistor output isolator designed to provide safe electrical isolation between low-voltage control circuits and high-voltage or noisy signal lines.
Each device contains an infrared LED that optically drives an NPN phototransistor, all enclosed in a small SMD 4-pin package suitable for high-density PCB designs.
This pack of 5 optocouplers is ideal for prototyping, repairs, and bulk electronic projects requiring multiple isolated channels.
